Cache-Based Compaction: A New Technique for Optimizing Web Transfer
In this paper, we propose and study a new technique, which we call cache-based compaction for reducing the latency of Web browsing over a slow link. Our compaction technique trades...

Amsaa: A Multistep Anticipatory Algorithm for Online Stochastic Combinatorial Optimization
The one-step anticipatory algorithm (1s-AA) is an online algorithm making decisions under uncertainty by ignoring future non-anticipativity constraints. It makes near-optimal decis...

Optimizing discrimination-efficiency tradeoff in integrating heterogeneous local features for object detection
A large variety of image features has been invented for detection of objects of a known class. We propose a framework to optimize the discrimination-efficiency tradeoff in integra...

Using Coherence Information and Decay Techniques to Optimize L2 Cache Leakage in CMPs
This paper evaluates several techniques to save leakage in CMP L2 caches by selectively switching off the less used lines. We primarily focus on private snoopy L2 caches. In this c...
